Giacomo Cusmano (15 March 1834 - 14 March 1888) was an Italian Roman Catholic priest and the founder of the "Congregatio Missionariorum Servorum Pauperum" which is also known as the "Boccone del Povero" (Morsel of the Poor).
Cusmano also established the Sisters Servants of the Poor.
He was beatified by Pope John Paul II on 30 October 1983.
His older sister was Vincenzina Cusmano, who joined his female religious order and was declared Venerable in May 2017, putting her on the path to beatification.
